Description
Triglycidyl ether triethoxy triazine (TGETET) epoxy resin cured by 1.6-diaminohexane (TGETET/DAH) and 4.4diaminodiphenyl methane (TGETET/DDM) was investigated as potential anticorrosive coating for carbon steel in sodium chloride medium. Polarization curves (PC) and electrochemical impedance spectroscopy (EIS) results displayed the protective efficiency of TGETET/DDM is higher than that of TGETET/DAH in 3.5 %NaCl medium. SEM data showed that both TGETET/DAH and TGETET/DDM could be significantly stopped the chloride ions attack due to adhesion between the protective layer formed on CS coated. Chemical reactivity tendency of TGETET/DAH and TGETET/DDM compounds were evaluated using global quantum chemical descriptors (GQCDs) and molecular dynamics simulation (MDs).
